Luke 18:1-8

18Then Jesus told them a parable about their need to pray always and not to lose heart.
2He said, In a certain city there was a judge who neither feared God nor had respect for people.
3In that city there was a widow who kept coming to him and saying, Grant me justice against my opponent.
4For a while he refused; but later he said to himself, Though I have no fear of God and no respect for anyone,
5yet because this widow keeps bothering me, I will grant her justice, so that she may not wear me out by continually coming.
6And the Lord said, Listen to what the unjust judge says.
7And will not God grant justice to his chosen ones who cry to him day and night? Will he delay long in helping them?
8I tell you, he will quickly grant justice to them. And yet, when the Son of Man comes, will he find faith on earth?
